13.11 Recommissioning the Inverter
If you have disconnected the inverter from all voltage sources and want to recommission it, proceed as follows.
Requirements:
• All circuit breakers in the AC distribution board must be open.
• All Sunny Island inverters must be connected correctly (see Section 6.7, page 63).
• All inverters must be closed (see Section 6.8, page 66).
• All Sunny Island inverters must be switched off.
• The fuse switch-disconnector of the battery fuse must be closed (see Section 6.9, page 67).
Procedure:
1. For systems with 1 Sunny Island, press the "On" button.
2. For systems with 3 Sunny Island inverters, press and hold the "On" button on the master until an acoustic signal
sounds.
3. For multicluster systems, press and hold the "On" button on each master until an acoustic signal sounds.
4. Establish a connection to the user interface of the inverter (see Section 8.1, page 104).
